menu.
- Press the cursor up/down to select FEATURES and press OK.
- Press the cursor up/down to select Child Lock and press OK.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

check menu and make sure speakers are not switched off and put your ear to speaker to see if even faint sound can be heard or a buzz.In menu check the speaker on or off feature and also that the sound is not muted.A few of these sets also have a feature for internal or external speakers and make sure it is set correctly.

Possible that the back light circuit has failed. It can be fault in the invertor circuit , normally there can be loss of voltage to the circuit , a failed transformer or drive.you can check on the line voltage and the drive output to confirm.If this seems okay the fault can be also related to the motherboard which might need assistance so as not to tamper the board with a false move.
Thanks for your help.

If you are using component cables change them out. It sounds like they're faulty. Try another device like a dvd player on a different input with different cables to see if the picture is still too red or too green. If so then the tv needs servicing. If not you can rule out the television.
